An example of a line and parabola are included. You should have at least 3 points ready to enter into MS Excel. Suppose I want to graph y=3x-2. Because this will be a line, I just need to find 3 points to enter in. Other graphs, such as parabolas, will require more points. If x=0, y=3(0)-2 = -2. Therefore, (0,-2) is a point on the graph. If x=1, y=3(1)-2=1 (1,1) is an additional point on the graph. If x=2, y=3(2)-2=4 (2,4) is an additional point on the graph. Let’s plot the points (0,-2), (1,1) and (2,4) and connect them with a line! You should always enter values in column A in increasing order, because that is the order they will be connected in MS Excel. Open up MS Excel. Enter in the points above as follows. Use your arrow keys to move between cells. Highlight all of the values with your mouse: Click on Insert and then on Scatter Then select the graph in the top right:
